- If an expression contains multiple operators with the same precedence and right-to-left associativity, the rightmost operation is performed first, followed by the next one to the left, and so on. - In Python, the exponentiation operator (`**`) and the assignment operators (`=`, `+=`,...
Operator associativity is thedirectionfrom which an expression is evaluated. For example, inta =1;intb =4;// a will be 4a = b; Take a look ata = 4;statement. The associativity of the=operator is from right to left. Hence, the value ofbis assigned toa, and not in the other directio...
64, 512, 512 Worksheet PrintWorksheet 1. What is the value of the following expressions? - print( 8/4/2 ) and print( 8/(4/2) ) (1.0, 4.0) (4.0, 1.0) (1.0, 1.0) (4.0, 4.0) 2. Which of the following operators has its associativity from right to left?
Associativity solves this. Multiplication is left associative, so we must first execute the expression on the left. Parentheses help us figure this out:let amount = (4 / 2) * 5Multiplication (*), division (/), remainder (%), add (+), subtract (-), logical AND (&&), logical OR (|...
You don't need to memorize everything here. Most of the time, the precedence and associativity of operators makes sense in itself. You can always come back to this article for reference when in doubt. Also, you can use parenthesis if you think it makes your code easier to understand.Previ...

After that, both a and b are zero, because due to right-to-left associativity (and equal precedence), the compiler sees it as (true ? a : (b = 7)), and will simply evaluate the a branch. If ?: was actually higher precedence than =, the value of a should be 7. Add parentheses...
